Then, is colon cancer a carcinoma?
Colorectal carcinoma is a cancer, or malignant tumor, of the large intestine, which may affect the colon or rectum.
Likewise, how long do you live after being diagnosed with colon cancer? Many colon cancer statistics involve a five-year survival rate. For example, if the five-year survival rate for localized colon cancer is 90 percent, that means that 90 percent of the people diagnosed with localized colon cancer are still alive five years after their initial diagnosis.
Besides, what part of colon is cancer most commonly found?
Colon cancer develops when tumorous growths develop in the large intestine. It is now the third most common type of cancer in the United States. The colon, or large intestine, is where the body draws out water and salt from solid wastes. The waste then moves through the rectum and exits the body through the anus.
What causes colon cancer?

In general, colorectal cancers tend to be slow growing, gradually enlarging and eventually penetrating the bowel wall. When they do spread, it is usually through invasion of nearby lymph nodes. In fact, cancer cells may enter a lymph node even before the tumor penetrates through the intestinal wall.What type of colon cancer is hereditary?
The two most common inherited colorectal cancer syndromes are hereditary nonpolyposis colorectal cancer (HNPCC) and familial adenomatous polyposis (FAP). They can affect men and women, and the children of people who carry these genes have a 50% chance of inheriting the disease-causing gene.Who is at high risk for colon cancer?
Both men and women are equally at risk for colon cancer. The cancer is most common among people aged 50 and older but can occur in patients as young as teenagers. Over 75 percent of colon and rectal cancers happen to people with no known risk factors, which is why regular screening is so important.How treatable is colon cancer?
Cancer of the colon is a highly treatable and often curable disease when localized to the bowel. Surgery is the primary form of treatment and results in cure in approximately 50% of the patients. Recurrence following surgery is a major problem and is often the ultimate cause of death.Where is colorectal cancer located?

The tests used to screen for colorectal cancer are described below.- Colonoscopy.
- Computed tomography (CT or CAT) colonography.
- Sigmoidoscopy.
- Fecal occult blood test (FOBT) and fecal immunochemical test (FIT).
- Double contrast barium enema (DCBE).
- Stool DNA tests.
